Generator Set Weekly Test and Inspection Checklist [FREE PDF]

Generator sets must be tested weekly under load conditions per NFPA 110 and NFPA 70E electrical safety standards to ensure reliable emergency power availability. OSHA 29 CFR 1910.303 and 1910.333 require that electrical equipment, including standby generators, be maintained in a safe operating condition and inspected by qualified personnel. Regular documented inspections support ISO 55000 asset management principles and reduce unplanned downtime during critical power events.

Pre-Inspection Safety and Lockout/Tagout

Verify all safety protocols are in place before beginning the inspection.

  • Has the area around the generator been confirmed clear of flammable materials and personnel hazards?
  • Are appropriate PPE items (insulated gloves, safety glasses, arc-flash rated clothing) worn for this inspection?
  • Is the generator tagged and documented appropriately if it must be taken offline for maintenance today?
  • Has the previous week's inspection log been reviewed for any outstanding deficiencies?
  • Is the generator room ventilation adequate and unobstructed?

Fluid Levels and Fuel System

Inspect all fluid levels and verify the fuel system is leak-free and adequately stocked.

  • Is the fuel tank level at or above the minimum required level (typically 75% capacity)?
  • Current fuel tank level (%):
  • Are there any visible fuel leaks at connections, filters, or the tank itself?
  • Is the engine oil level within the acceptable operating range on the dipstick?
  • Is the coolant level in the radiator overflow reservoir within the MIN/MAX range?
  • Are there any visible oil or coolant leaks beneath or around the engine?

Battery and Starting System

Verify the starting batteries and charging system are fully operational.

  • Is the battery charger plugged in and indicating a normal float/charge status?
  • Battery terminal voltage reading (VDC):
  • Are battery terminals free of corrosion, cracks, and loose connections?
  • Did the generator start within 10 seconds during the test run (per NFPA 110 requirement)?
  • Are battery cables intact with no fraying, cracking, or damage to insulation?

Weekly Test Run Under Load

Document the results of the mandatory weekly exercise test.

  • Was the generator exercised under load for a minimum of 30 minutes this week?
  • Output voltage during test run (VAC):
  • Output frequency during test run (Hz):
  • Did the generator operate without abnormal vibration, smoke, or alarms during the test?
  • Engine coolant temperature during steady-state test run (°F):
  • Oil pressure reading during test run (PSI):

Automatic Transfer Switch (ATS) Inspection

Verify the ATS is functioning correctly and transferring loads as expected.

  • Did the ATS successfully transfer the load to the generator within the required time delay?
  • Is the ATS enclosure door closed, latched, and free of physical damage?
  • Are all ATS indicator lights functioning and showing normal status?
  • Did the ATS retransfer to utility power smoothly after the test with no alarms?
  • Is the ATS wiring and terminal block area free of visible overheating, discoloration, or burnt odor?

Physical Condition and Housekeeping

Assess the overall physical condition of the generator set and surrounding area.

  • Is the generator enclosure and base frame free of cracks, corrosion, and structural damage?
  • Are all access panels, covers, and guards in place and properly secured?
  • Is the exhaust system free of leaks, rust, and damage, with no obstructions at the exhaust outlet?
  • Are air intake filters visually clean and unobstructed?
  • Is the generator room floor free of fluid spills, debris, and slip hazards?

Documentation and Corrective Actions

Record findings, deficiencies, and any corrective actions taken or required.

  • Were any deficiencies identified during this inspection?
  • Describe all deficiencies found and corrective actions taken or scheduled:
  • Has a work order been created for any items requiring follow-up maintenance?
  • Additional inspection notes or observations:
  • Has a photo of any damage or deficiency been attached to this report?
